Redirect the per-channel build scratch to /dev/shm and skip UPX, a big win when
building from a USB stick / SD card (I/O-bound on flash):
- TMPDIR + PIP_CACHE_DIR -> tmpfs
- PyInstaller: --workpath -> tmpfs (PYI_WORKPATH); UPX off via TESTIUM_NO_UPX
- Flatpak: build dir + ostree repo -> tmpfs (FLATPAK_BUILDDIR/REPODIR); the
.flatpak-builder download cache stays on disk
- AppImage: bind-mount a tmpfs dir at the in-container AppDir path
(APPIMAGE_APPDIR_TMPFS)
Scratch is freed on exit. Each build.sh honors the env vars with on-disk
defaults, so behavior is unchanged without --ram. With --ram, prefer --serial
on RAM-limited machines (flatpak+appimage are ~1 GB each).

Collects all four artifacts under <repo>/dist/ (PyInstaller and Flatpak
renamed to testium-<version>(.suff); wheel and AppImage keep PEP 427 /
appimage-builder original names). Re-uses scripts/build_env.sh and
set_env.sh, same venv as run.sh. AppImage build.sh now picks the actual
output file dynamically instead of a hardcoded lowercase name.
build.sh runs appimage-builder in a Debian Bookworm container (Podman or
Docker) so it works on Arch / non-Debian hosts. Uses single src/requirements.txt;
TESTIUM_VERSION exported in runtime.env.
